Question

我应该添加一个多边形橙色鼻子和一个多边形黑帽子，以及写给他的围巾，但无法弄明白。这就是我到目前为止所拥有的。我似乎无法想象我是否需要使用fillpolygon或什么。

public class SnowMan  extends Applet
{

    public void paint (Graphics frame)
    {
        //  set up some constants
        final int MID = 150;    // middle of the snowman
        final int TOP = 50;     // top of the snowman

        //  need to set the background colors
        setBackground (Color.cyan);

        // color the ground
        frame.setColor (Color.lightGray);
        // the ground is a blue rectangle
        frame.fillRect (1, 175, 500, 150) ;



        //  draw three large snowballs to make up snowman
        frame.setColor (Color.white);

        // draw head
        frame.fillOval (MID - 20, TOP, 40, 40);
        // draw middle (upper torso)
        frame.fillOval (MID - 35, TOP + 35, 70, 50);
        // draw base (lower torso)
        frame.fillOval (MID - 50, TOP + 80, 100, 60);

        //  draw in features of snowman
        frame.setColor (Color.black);

        //  draw eyes
        // draw left eye
        frame.fillOval (MID - 10, TOP + 10, 5, 5);
        // draw right eye
        frame.fillOval (MID + 5, TOP + 10, 5, 5);

        //Draw Buttons
        frame.fillOval (MID -2, TOP + 50, 5, 5);
        frame.fillOval (MID -2, TOP + 60, 5, 5);
        frame.fillOval (MID -2, TOP + 70, 5, 5);


        //  draw arms
        // draw left arm
        frame.drawLine (MID - 25, TOP + 60, MID - 50, TOP + 40);
        // draw right arm
        frame.drawLine (MID + 25, TOP + 60, MID + 55, TOP + 60);

        //  draw hat
        // draw brim of hat
        frame.drawLine (MID - 20, TOP + 5, MID + 20, TOP + 5);

        frame.fillRect (MID - 20, TOP + 35, 40, 10);


        // draw top of hat
        frame.fillRect (MID - 15, TOP - 20, 30, 25);

        frame.setColor (Color.red);

        // draw mouth
        frame.drawArc (MID - 10, TOP + 20, 20, 10, 190, 160);


    }
}

只需创建一个多边形并绘制它

Error: Could not find or load main class org.elasticsearch.tools.JavaVersionChecker
Elasticsearch requires at least Java 8 but your Java version from /bin/java does not meet this requirement

您必须将鼻子设置在正确的位置，因此您必须调整public void paint (Graphics frame) { ... //three points form a nose int[] xs = new int[]{10, 0,10}; int[] yx = new int[]{0, 10,10}; //uhm - ugly triangle 'carrot' nose //TODO: set color before drawing //create polygon from three points Polygon p = new Polygon(xs, ys, 3); //draw the polygon frame.fill(p); }和xs值......

无法添加多边形并在java中写入我的雪人
